C# - Dynamic Text Being Stored In Viewstate?
Aug 19, 2010
My asp.net application has a function that returns the HTML for the navigation menu for the user by getting it from a database
currently, I am storing the text in a session variable when the session begins and then use it to set the innerHtml of the navigation div on the on_load method.
The problem is that the pages now contain the
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPD..
with the value being 7000 characters long.
Is there any better way to do this or a different way to store and retrieve values without them being stored in the viewstate ?
The code is just this:
Session["menuHTML"] = (new NavMenu().GetMenuHTML());
navMenuDiv.InnerHtml = Session["menuHTML"].ToString();
The div is declared as
<div id="navMenuDiv" class="navMenuDiv" runat="server"></div>

I have an asp.net web form, and on it I have two controls (well, more than these two but we'll focus on these) - the first is an asp:dropdownlist and the second is an asp:table.
Both of these controls are declared on the HTML side, and filled (child controls added) in the code-behind page.
My simple question (hopefully with a simple answer) is this:
Why does the viewstate persist for the dropdownlist, and NOT for the table?
I have to fill the table on every page load, but I can fill the dropdownlist once (using Not Page.IsPostBack), and it persists.
NOTE: I have read about the lifecycle of ASP.NET pages, and I have tried placing these same calls in the Init() and PreInit() page events with the same results.

I have a question about retrieving the values from dynamic created controls. I'am using an wizard witch collects it data based on the steps in the wizard. At a certain wizard step i generate dropdownlists and textboxes depending on some records from a database. At this point no problem, the controls are created perfect. When i press the next button on the wizard i read out the eventarg e.currentstepindex, iterate throug the gridview witch is displaying the controls and try to find the control with "findcontrol" function.
The controls are "nothing" and i cant access them. THe source code of the page lets me show that the controls are there and that they have the assigned ID's.I investigated on google what the problem could be. I has to do with the viewstate and i have to regenerate the controls on page_load.

I am creating a gridview dynamically in a custom control and adding it to a Panel. I set the EnableViewState = true. The problem is that on a page postback the GridView does not seem to retain its values. If I add a GridView through the UI then the viewstate is preserved. The problem seems to occur when it is put dynamically only.

Setup:
My page has a drop down whose values are dynamically populated. Based on which item is selected, a number of TextBoxes are dynamically created during runtime.The user then fills in information into the textboxes and clicks a submit button.
Problem:
After postback from the submit button, I need to again dynamically create the TextBoxes during Page_Init (BEFORE LoadViewState) so that after the ViewState loads, my Button_Click event can save/do whatever with the user input. PROBLEM is, I cannot recreate the textboxes based on the selection in the dropdown, because the dropdown hasn't been "selected" yet by LoadViewState.
SO, how can I read from the view state, create my textboxes, then let the viewstate populate the textboxes, and then the Button_Click will use the values??
The one thing I've attempted is to override the LoadViewState function so that I can read from the view state, create the boxes, and then load the viewstate again. This did NOT work, because the debugger never seemed to hit my overridden function.

I have a set of dynamically-created (IE: by code) controls on my web page. Depending on which options the user decides to go (Edit/New), those controls are re-created with the appropriate information (IE: "with values" with Edit, "without values" with New).
Here's the situation:
- I create my controls in InitComplete when it comes to save the data (both on Edit/New) contained within the controls.
- I create my controls in PreLoad when it comes to load them initially (Both on Edit/New) in order to avoid the ViewState to kick in.
However, despite creating the controls after the ViewState has been applied (technically), the controls still somehow retain the pre-postback's information. IE: if I have options 2 and 4 selected and I choose "New", which should show the options without being selected, they remain selected no matter what. And this is true despite changing their values in the PreLoad state. From my understanding, creating a control in this fashion and at that point in the page lifecycle should override any values the ViewState might have had for those controls. I have also tried to disable the parent's control viewstate (Table.EnableViewState = false) again, to no avail.
I've tried using the Me.ViewState.clear() and Me.ClearChildViewSate prior to loading the initial values as well, but again all for naught. I do understand that any control created after the Init phase of the lifecycle has to play "catchup" with the current state, however I would expect that clearing the ViewState prior to creating the controls would fix this issue. It doesn't seem to.

I have a project where I need to create menu buttons from a list in SQL Server. The problem I am having is that I need to add code to the text of those buttons. So there would be a birthday button and it should display the number of birthdays within the next two weeks or a button with the number of upcoming events.
Clarification:
There is no code yet, just some requirements. What I am doing is querying a table to get the list of buttons to display. Now each of these buttons may have dynamic text, for things like count of birthdays, events,etc... I am trying to see what the best way would be to handle this. Should I embed a snippet of code to go along with the menu item to execute when I iterate over the menu items? Maybe I should build a javascript file to go along with the code, which I add code to query a service for certain menu items?

My datasource is an ado data table that I have convert to a new data table so that each row in the original table is now a column with 1 row in my new table. I then bind the new datatable and create dynamic template fields with a text box where I bind the values. My problem is, when I try and retrieve the values changed by the user in the rowcommand event, the template columns no longer exists.
Does anyone know how i can retrieve these values? I've read over and over that you have to rebind the grid on each postback when you use dynamic templates, but I'm not sure how to do that and retrieve the values entered in the text boxes on the client side.

I need to update a table with values from a listbox. I am trying to create as many parameters as there are items in the list, my code below, but how do i name them differently? so that they dont' overwrite each other?
For Each item As ListItem In ris
Dim pID As New SqlParameter("@userid", SqlDbType.Int)
pID.Value = objFormat.CheckSQL(item.Value)
myCommand.Parameters.Add(pID)
Next
and on the SQL side, is it possible to write an update statement, that will take a dynamic number of parameters?
so for example, i need to update multiple users with the same value in the "active" field...

In my ASP.NET page I have to dynamically choose and load a custom control, depending on the selected value in a dropdownlist.However I encountered the following problem: When the parameters of the dynamically loaded control are changed, and then the selection in the dropdownlist is changed( thus forcing me to load a different dynamic control the next time the page reloads ), I end up with a "Cannot load ViewState" exception.I assume that this happens because the ViewState is trying to restore the parameters of the old control and it doesn't find it. So , is there any way to stop the viewstate from attempting to restore the state of the non-existig control?

Now here is the weird thing. First i am running it locally on the built in vs2008 web server.I load my control in fine, do a postback from a linkbutton, locally on my machine it all works fine, no issue.However when it goes onto my host, it falls over with the message:
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.Now i also load controls dynamically and use postbacks and things in the admin area of the site...and that works fine, however my front end just keeps failing? See the code behing below:

I have been getting this error a lot lately with some of my users, and I had a couple of concerns with view state and I have read so many articles but I am still lost..
1. I use masterpage on all the pages and I need viewstate for some of the pages but..
There is a page where a user will fill out the information and then submit this data to a cgi server, and it is where I get most of the Client Disconnected errors, what would happen if I disable viewstate when they click on that button?
Now when a user browses from one page to another, does the view state from the previous page get deleted? If not how would I delete it?
Does the master page have its own viewstate? Would I be able to make sure none of items on my master page are using the viewstate?

I have a shopping cart page (Cart.aspx) that has a button that will (sometimes) post to a third party payment gateway, if payment is necessary. The payment gateway will process the payment and then do a silent post to my website (Order.aspx) so I can update the order status.
Order.aspx always throws an invalid viewstate error, even though viewstate is disabled on the page.
What's happening is that Cart.aspx (which has viewstate enabled) posts to the payment gateway, and the gateway will post it back as part of the silent post. Even though Order.aspx has viewstate disabled and validation disabled, it still tries to validate the __viewstate field it's being given.
I know setting EnableViewState=false will disable the rendering of the __viewstate field, but if another page provides the field, shouldn't it still skip validation? I tried calling ViewState.Clear() on the Page_Init event of Order.aspx, but ViewState is apparently empty. how to get around this? I don't want to disable ViewState on Cart.aspx (in some cases it may be necessary), but I can't figure out how to clear it on Order.aspx.
